I hide the explanation part because I do not know should I expunge those information, or include them in the articles.

1) The room of meaningless

What is it?

A room in a college, the foundation takes over the college to contain the SCP, and use it as a torture room to get information from other GOI members.

What it do?

There was a paper on the door of the room which stat “_ is not allowed”, you can write anything in and the person in the room will not be allowed to perform it. After several experiment include bending the law of nature which resulted [data expunged], the foundation banned any experiment toward this SCP and use it as the torture room.

The [data expunged] is, nothing happened. This room is totally useless beside it hypnotize people inside it that they are not allowed to do certain thing. So if you write down “breathing is not allowed”, the victim will think they can’t breathe inside the room, but they will not die and eventually breathe, just like you cannot choke yourself to death.

2) World fastest restaurant

What is it?

A restaurant in Hong Kong, which when people get in, they get out immediately. The foundation took over the blocks and send D-class as costumers for experimental purpose.

What it do?

D-class claimed they do not feel any anomaly inside it, beside all time measure devise not working in the restaurant (clock, camera, etc), the foundation start letting researchers get in to understand how the restaurant alter the speed of time, and one of the researchers became crazy and reported he see himself all over the place, exist in muti-place and doing various of thing simultaneously, which make his sensory overloaded.

The restaurant does not alter time, but disable causality. So you do not need to do things step-by-step, the ultimate way to save your time. The poor researcher is just seeing the reality inside it, while other people failed to do it.

3) Digging through the time

What is it?

An archaeological site that someone dig up bones of a dinosaur, but find out it just dead few days ago.

What it do?

As the digging goes on, they found more things under the ground, includes corpses, animals, blood, feces, etc. All human DNA from the corpses do not match anyone in the history and the DNA in blood and feces do not match any creatures in earth.

After reading the whole book, extra limbs and organ with no sensory and no function will glow all over victim’s chest, and the victim cannot consume any nutrients from food or substance and died for malnutrition eventually.

1. No. The Foundation isn't the sort of organization to use an SCP (located in a public institution no less) as a torture chamber. Why the hell would it bring GOI agents to a less secure, anomalous location when mundane means can be found to interrogate people just as efficiently in a secure site? Plus, this sort of suggestion thing has been done before.

2. Not a huge fan of it. It's another "place that makes you go crazy" sort of deal, with the fairly non-interesting twist to it.

3. Might possibly work, but you're making it sound way more grimdark than it should be. A beast that slowly eats time can work, but it doesn't have to be all "evil corpses blood gore!". Have it eat something else maybe, something less predictable.

4. Body horror isn't my thing, and this one looks fairly run of the mill.
